Abstract
A contactless authentication system includes: at least one illumination apparatus that projects illumination light onto a portion of a hand, the portion being not in contact of an object, the illumination light containing a light component in a wavelength range greater than or equal to 1380 nm; and an imaging apparatus that obtains at least one selected from the group consisting of a fingerprint image and a palm print image as authentication information by imaging the light component in the wavelength range in reflected light generated by reflection of the illumination light from the portion of the hand.
